Chapter 1: Problem 11

Plot the given point in a rectangular coordinate system. $$\left(\frac{7}{2},-\frac{3}{2}\right)$$

Short Answer

Expert verified
The point \(\left(\frac{7}{2},-\frac{3}{2}\right)\) is found in the fourth quadrant, 3.5 units to the right of the vertical axis (y-axis) and 1.5 units below the horizontal axis (x-axis).

Step by step solution

01

Understand the Cartesian coordinate system

A Cartesian coordinate system represents each point in the plane by an ordered pair \((x, y)\), where 'x' is the abscissa (horizontal coordinate) and 'y' is the ordinate (vertical coordinate). The 'x' value (abscissa) represents the horizontal distance of the point from the origin (either to the right (+) or the left (-)), and the 'y' value (ordinate) represents the vertical distance from the origin (either upwards (+) or downwards (-)).
02

Decoding the given point

The given point \(\left(\frac{7}{2},-\frac{3}{2}\right)\) can be read as 'x' is half of 7 (which is 3.5) and 'y' is negative half of 3 (which is -1.5). This means we move 3.5 units to the right and 1.5 units down from the origin (0,0).
03

Plot the point

Plot the point (3.5, -1.5). Start at the origin, move 3.5 units to the right and from there move 1.5 units down. Mark this point.

Most popular questions from this chapter

Sketch the graph of \(f\) using the following properties. (More than one correct graph is possible.) \(f\) is a piecewise function that is decreasing on \((-\infty, 2), f(2)=0, f\) is increasing on \((2, \infty),\) and the range of \(f\) is \([0, \infty)\)

Explaining the Concepts: If a function is defined by an equation, explain how to find its domain.

Determine whether each statement is true or false If the statement is false, make the necessary change(s) to produce a true statement. Prove that if \(f\) and \(g\) are even functions, then \(f g\) is also an even function.

Find and simplify the difference quotient $$\frac{f(x+h)-f(x)}{h}, h \neq 0$$for the given function. $$f(x)=7$$

114\. If \(f(x)=x^{2}-4\) and \(g(x)=\sqrt{x^{2}-4},\) then \((f \circ g)(x)=-x^{2}\) and \(\left(f^{\circ} g\right)(5)=-25\) 115\. There can never be two functions \(f\) and \(g\), where \(f \neq g\), for which \((f \circ g)(x)=(g \circ f)(x)\) 116\. If \(f(7)=5\) and \(g(4)=7,\) then \((f \circ g)(4)=35\) 117\. If \(f(x)=\sqrt{x}\) and \(g(x)=2 x-1,\) then \((f \circ g)(5)=g(2)\) 118\. Prove that if \(f\) and \(g\) are even functions, then \(f g\) is also an even function. 119\. Define two functions \(f\) and \(g\) so that \(f^{\circ} g=g \circ f\)
